Sub-slab depressurization is a technique used to manage soil gases like radon beneath concrete foundations. By creating a low-pressure zone under the slab, often with a fan and vent pipe, it prevents gases from seeping into homes. It's a practical retrofit for existing buildings, installed through the slab to connect with gravel or soil below, keeping indoor air safer without major disruption.

After installing a radon mitigation system, it's crucial to retest your home to ensure the levels dropped below the action limit. Wait at least 48 hours after turning on the fan, and run the test for a minimum of two days during normal living conditions. If the radon still tests high, you may need to adjust the system or add a sealant around foundation cracks.
